My devices can not connect to 2.4Ghz wifi any more.

My older devices which use 2.4Ghz wifi can no longer connect to my wifi. Devices using 5Ghz connect with no issues.

After logging into the HUB I can see that both 2.4 and 5GHz networks are enabled but when I try to connect with my older phone I just get a message on the phone 'connection failed' I tried with a few different older devices with the same result - they cannot connect.

Morning,

Thank you. When did you change this? Does it try to change the channel back again?

Restarting didn't help.

I changed channel from 11 to 6 and it works now. On channel 11 it does not work at all despite this channel being least busy. Is there a reason why channel 11 suddenly stopped working?

Hi witor,

How are you getting on?

Thanks

Morning,

I'm sorry to hear this. Have you tried rebooting the router and then retesting this again? 

Thanks
